FILTER.

Application'filed April 26, 1915.

To all whom it may concern:

Be it known that I, AMos N. HAMLET, a citizen of the United States, residing at Elk Point, in the county of Union and State of South Dakota, have invented certain new and useful Improvements in Filters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in filters.

The object of the present invention is to improve the construction of rain water filters and to provide a. simple, practical, and comparatively inexpensive filter of this character adapted to be readily applied to either side of a house and to be reversed to accommodate a rain spout at either end of it without necessitating any alteration in its construction.

A further object of the invention is to provide a rain water filter adapted to afford ready access to its interior and capable of being easily cleaned.

lVith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings Figure 1 is a vertical sectional view of a rain water filter constructed in accordance with this invention, Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1, Figs. 3 and at are detail sectional views illustrating the construction of the inlet openings and the removable slidable closure therefor.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention 1 designates an outer casing designed to be constructed of galvanized sheet metal or other suitable material and Specification of Letters Patent.

Serial No. 23,967.

receive a slidable closure 8 which may be arranged on the flanges of either of the inlet openings 5 and 6 to enable a rain spout 9 to be connected with either end of the casing. By this construction the filter may be located ateither side of a building and connected at either end with the rain spout and one inlet opening is uncovered to receive the rain spout 9 and the other is closed by the slidable cover or closure 8.

lVithin the outer casing is arranged an inner reversible casing 10 composed of imperforate side walls 11, an imperforate bottom 12, an end wall 13 and foraminous transverse partitions let and 15. The inner reversible casing which may be constructed of galvanized sheet metal or any other suitable material is arranged upon the bottom of the outer casing with its bottom 12 supported above the bottom of the outer casing by lower extensions 16 of the side walls of the inner reversible casing. The sides of the reversible casing are also provided at one end of the said inner casing with extensions 17 located at the upper portions of the side walls and the end wall 13 is composed of upper and lower vertical portions 18 and 19 and inclined connecting portions 20, suitably connected with the side walls at the said ex tension 17 thereof. This construction provides an upper extension at one end of the casing and a recess 21 below the extension which is of a length to extend beneath and slightly beyond the lower end of the rain spout 5 so that all of the water passing downward through the same will enter the inlet chamber or compartment 22 between the front wall 13 and the inner foraminous partition 14:. The partitions 14c and 15 are preferably constructed of woven wire and the space between the same forms a filter compartment adapted to receive filtering material 23 such as charcoal or the like. The water entering the inlet chamber or compartment passes through the filtering material and leaves the inner casing at the transverse partition or wall 15.

The outer casing is provided at the bottom at one end with a short pipe or nipple section 24 piercing the bottom and extending upwardly and downwardly therefrom. The upwardly extending portion 25 receives a screen 26 of closely woven wire. The screen which is of cylindrical form is open at the bottom to fit over the projecting upper portion 25 of the nipple 24: and the depending portion 27 of the nipple is threaded for the reception of a threaded portion 28 of a cistern pipe 29.

The slidable lid or cover is readily removable to afford access to the interior of the outer casing and the inner casing is adapted to be readily removed and reversed to arrange its extension end portion and the water inlet compartment or chamber beneath the rain spout which may be located at either of the openings 5 and 6. It will be seen that this construction will save time and labor in applying the filter to a building and that it may be located at either side of a building and may have the rain spout connected with either end of it without altering its construction. The outer casing is also provided at the bottom with a flanged drain opening 30 normally covered by a screw cap 31 which is adapted to be removed for cleaning out the outer casing of any sediment which may collect therein.

What is claimed is 1. A filter of the class described including an outer casing provided at the top with spaced inlet openings adapted to receive a rain spout to permit the rain spout to be connected with opposite portions of the casing, the latter being provided at the bottom with an outlet, and a reversible inner casing provided with a filter compartment and having a water inlet compartment or chamber arranged to extend beneath either one of the inlet openings.
